About Toybox: SwiftUI & Metal Lab
Toybox is a hand-crafted showcase of SwiftUI animations and Metal shader experiments — a small sandbox where each screen is an interactive visual idea you can open, run, and play with. Open the app and you're greeted with a list of screens. Tap one and a self-contained piece comes to life: cellular automata, generative patterns, particle waves, mosaics, badge animations, the Apple logo reimagined, and many more. Every screen is a single, focused experiment built with modern SwiftUI and, where it makes sense, custom Metal shaders. What's inside • Dozens of bite-sized visual experiments • SwiftUI animations built on the latest APIs • GPU-driven effects written in Metal Shading Language • Adaptive layout that feels at home on iPhone, iPad, and Mac • Tag-based filtering to find effects by category Who it's for Designers looking for a moodboard of motion and graphics ideas. Developers studying how a particular SwiftUI or Metal technique is put together. Anyone who simply enjoys playing with visual toys. Built with • SwiftUI and the @Observable model • Metal shaders compiled by a Swift Package Manager build plugin • A modular, package-driven architecture Try it before you install — App Clip Not ready to commit to a download? Open Toybox as an App Clip straight from a Safari Smart App Banner or a shared link. No App Store visit, no waiting — a curated selection of Metal shader effects runs immediately. If you like what you see, the full gallery is one tap away. Toybox is open-source and growing — new screens are added regularly. If you're curious about what modern Apple platforms can do visually, open it up and start tapping.
